VAG-COM - Getting Started
Thank you for purchasing VAG-COM, which allows you to turn a Windows-based PC into a
sophisticated diagnostic tool for VW/Audi/SEAT/Skoda models from 1990-2007.
Read This First!
Before plugging anything in,
you must install VAG-COM software.
Step #1
Go to our website and click on Download at the top of the screen to download and install
the latest version of VAG-COM:
www.Ross-Tech.com
Follow the onscreen
instructions and allow
VAG-COM to install in its
default directory. ►
The VAG-COM Pro-Kit comes with a CD containing our software as well but if possible it is
always a good idea to download the latest version from our website.
◄Step #2
Connect the Serial end of your
Serial Interface or the USB end of
your USB Interface to the correct
port on your PC. If your PC is
further from the vehicle than 6
feet, connect an approved
Extension Cable between the PC
and the Interface. The
appropriate extension is included
in the Pro-Kit and additional ones
are available from our web store.
3
Getting Started cont.
Step #3 (USB Only) ►
If you are using a Serial Interface then you can
proceed to step #4. If you are using a USB
Interface, a message like this should pop up: ►
Click on the Found New Hardware message and the Found New Hardware Wizard should
start up. If you are prompted with the choice, pick “No, Not This Time” when asked if you
want to connect to the Internet to search for drivers. Select "Install the software
automatically (Recommended)" then click [Next >]
The process should be automated but you may need to click “Continue Anyway” part way
through the process. If you are using Windows 98/ME then you should follow the USB
Driver Installation Instructions that should automatically pop up on your screen.
If, for some reason, you installed the USB Interface without following the above
instructions, and VAG-COM does not work correctly, go into your PC’s Device Manager
while the USB Interface is connected.
In Windows XP, you can find the Device Manager by right-clicking on My Computer. Select
Manage to bring up Computer Management. On the left side of the screen under System
Tools, select Device Manager.
Find the “VAG-COM Compatible USB Interface” and delete it. Check under “Other
Devices”. Then, unplug the USB Interface from your PC, wait 5 seconds and plug it back in.
Proceed with the installation starting on Page 1.
Step #4 ►
Connect the car end of your
Interface to your vehicle’s Diagnostic Port. ►
◄ If your vehicle has a 2x2 port (some pre-1996
vehicles), then use the optional 2x2 Adapter between
the Interface and the ports in the car. This is included
in the Pro-Kit.
Turn the vehicle’s ignition switch to the ON position. Make sure the key is turned far
enough that the dash lights are fully illuminated. The engine may either be running or
stopped.
4
Step #5 ►
Start the VAG-COM program on your PC through either the
Start Menu or the icon on your Desktop.
◄ Step #6
From the Main Screen in
VAG-COM click the
[Options] button to go into
the Options screen.
Step #7►
Once you are in the
Options Screen, Select
the correct port for your
PC’s Serial Port (typically
COM1 or COM2) or USB
Port (USB) and click the
[Test] button. Ensure that
VAG-COM finds your
interface.
5
Step #8
You should see a message like the one above.
•
•
•
•
•
If the Interface Status is “Not Found!” check the connections at the car and PC.
Make sure both are plugged in securely. Serial Interfaces get their power from
the vehicle so they will not be recognized at all if not plugged into the car.
Adapter Type should always be “Ross-Tech” followed by the name of the
Interface.
Version indicates the firmware version of your Interface. It may be updated by
new versions of VAG-COM, if so follow the prompts on the screen.
If K1 or K2 status are not “OK”, you may have a short or an open circuit in the
car’s diagnostic port, most likely caused by the Aftermarket Radio Problem, See
the Aftermarket Radio Problem page on our Website for more info:
http://www.ross-tech.com/vag-com/aftermarket-radio.html
CAN status indicates whether or not the vehicle uses CAN-Bus for diagnostics.
Once you have tested successfully, click [OK] then click [Save] to apply this configuration,
you will be returned to the Main Screen.
Click on [Select] to view the Select Control Module Screen. Select one of your car's
Control Modules such as Engine.
Note: Your car will not have all the Control Modules listed in VAG-COM, only the ones that
were installed in your vehicle. See the Applications Page for your car on our Website for
more info:
www.Ross-Tech.com/vag-com/cars/applications/
After VAG-COM has connected, click on [Fault Codes] to check for Fault Codes (DTC’s).
Repeat the process for each of your car's Control Modules. If you encounter problems, see
the FAQ on our website first:
http://www.ross-tech.com/vag-com/vag-com-faq.html
If you still have problems, feel free to contact us with full details about your PC and vehicle,
preferably while you are in front of both:

VAG-COM - Main Screen
This screen appears when you start VAG-COM by clicking the shortcut on your Desktop or
by selecting VAG-COM from the Start Menu. These screen-shots were taken using
Microsoft Windows Vista with the "Aero" style. If you are not using Vista Aero, expect the
screens to look different but the functions will be the same.
On this screen, you have 8 buttons that you can click:
[Select]
[Auto-Scan]
[Control Module Finder]
[OBD-II]
[Applications]
[Options]
[About]
Each of the above buttons is described in its own section in this manual.
[Exit] (This closes the VAG-COM program)
7
VAG-COM- Select Control Module
The various computers in the car are called “Control Modules” or “Controllers”. On this
screen, you select which Control Module you want to "talk" to. To establish communications
with a particular Control Module, simply click on the appropriate button. For example, click
on the button for [01 – Engine] to connect to the engine controller. VAG-COM has buttons
for all control module addresses currently supported by the factory diagnostic tools.
Module Tabs
Each tab on the top of this screen contains a number of different controllers grouped by
category: Common, Drivetrain, Chassis, Comfort/Conv., Electronics 1, and
Electronics 2. Each possible controller is listed as a number and a description, i.e.,
[01-Engine]. The number corresponds to the controller number that you'd find in your
Factory Repair Manual in the instructions for using a VAG-1551 or other factory diagnostic
tool.
Direct Entry
You can also enter any address manually. Simply put in the address and click [Go!]
To return to the Main Screen, click [Go Back]
Note: Your car will not have all the Control Modules listed in VAG-COM, only the ones that
were installed in your vehicle. See the Applications Page for your car on our Website for
more info:
www.Ross-Tech.com/vag-com/cars/applications/
8
VAG-COM - Open Controller
This screen will appear when VAG-COM is establishing communications with any of the
Control Modules shown on the Select Control Module screen.
Comm Status Shows the status of the current communications session. Once
communications have been established:
9
•
IC= Shows the number of times the session has been initialized. If IC increases
beyond 1, communications are less than 100% reliable.
•
TE= is a counter of transmitter errors within individual packets. TE greater than 0
can indicate unreliable communication.
•
RE= is a counter of receive errors within individual packets. RE greater than 0
can indicate unreliable communication.
•
Protocol indicates whether the controller speaks KWP-1281 , KWP-2000 , or
CAN-Bus. (See the Function Chart in Appendix E in this manual for more
information).
•
A rotating cursor shows that communication is active.
Open Controller cont.
Controller Info
Once the communications session has been established, all of the Control Module’s
"Identification" data is presented here.
•
VAG Number is the VW/Audi part number for this controller. All of the digits, both
numbers and letters, make up the part number. In some cases this number may
be different from the number on the sticker on the module itself, specifically if the
module has been reflashed by a dealer per a service campaign.
•
Component contains more identification information about the controller and
may contain a version number for the controller's internal firmware.
•
Soft. Coding is the Software Coding that determines various options for the
controller. Note: Some older Control Modules are not "codeable" and you may
see a Bosch part number or other information in this field.
•
Shop # identifies the WorkShopCode ( WSC) stored in the scan-tool that
performed the last Coding or Adaptation procedure in this Control Module.
•
The Extra fields can show VIN and Immobilizer information or slave controller
part numbers in some vehicles.
Basic Functions
This grouping of "Safe" functions are used to read various data from the Control Module.
Advanced Functions
These functions are capable of making various "programming" changes to the Control
Module. You should refer to the Factory Repair Manual for your particular car (or to other
documented procedures) before "playing" with these functions. It is completely possible to
render your vehicle inoperable or damage components if you make changes in this section
without the correct information and training.
It is normal for some buttons to be grayed out on some control modules. This is an
indication that the control module in question doesn't support those functions. Each of the
function buttons is detailed on the following pages.
Use [Close Controller, Go Back - 06] to properly close the communications session and
return to the Select Control Module screen.
10
VAG-COM - Fault Codes
(VAG 1551/1552 functions 02 and 05)
On this screen, VAG-COM shows you any DTC's (“Diagnostic Trouble Codes” or Fault
Codes). VAG-COM shows the DTC numbers and also decodes each DTC into
meaningful text.
At top of the screen is shown the VAG Number and Component number as found on the
Open Controller screen.
The Display Freeze Frame Data checkbox adds Freeze Frame data for Fault Codes on
control modules using the KWP-2000 protocols. Note: Not all control modules fully support
this; very few cars can currently handle freeze-frame data using the VAG proprietary
protocols. In vehicles that do not support Freeze Frame, that checkbox will not be present.
11
Fault Codes cont.
One component of Freeze Frame data is the Fault Priority number as described below:
Number
Meaning
1
The fault has a strong influence on driveability, immediate stop is required.
2
The fault requires an immediate service appointment.
3
The fault doesn't require an immediate service appointment, but it should be
corrected with the next service appointment.
4
The fault recommends an action to be taken, otherwise driveability might be
affected.
5
The fault has no influence on driveability.
6
The fault has a long term influence on driveability.
7
The fault has an influence on the comfort functions, but doesn't influence the
cars drivaebility.
8
General Note
VAG-COM tells you how many fault codes have been found and displays each of them.
The 5-digit or 7-digit number is a standardized VAG fault code, which can be searched in
the Factory Repair Manuals. The text is a description of the part and failure mode. The
letter and number combination in parentheses is the DIN Component Identifier. This is
followed by elaborators describing the condition of the fault. The second line contains the
P-code, or generic OBD-II code (if it exists, there are thousands of VAG codes without
generic OBD-II equivalents).
[Print Codes] will print a Fault Code Report. If your PC is not connected to a printer when
this button is pressed, be sure to use Windows to set the printer to "Work Off-Line" first!
Later, when you connect the PC to a printer, un-check "Work Off-Line" to print the report.
[Copy Codes] will copy your fault codes to Windows Clipboard. Once you have pressed
the Copy Codes button, you may paste the results into the application of your choice, such
as MS Word or Notepad.
[Save Codes] will save a plain-text Fault Code Report to the Logs directory of your PC,
typically: C:\ross-tech\vag-com\Logs\
[Clear Codes - 05] will erase the DTC's from the Control Module's memory. Be aware,
this does not fix the problem that caused the fault! DTC's should only be erased after
correcting the condition(s) that caused them in the first place. Note: There is no way to
erase individual DTC's while leaving others alone. This is not a limitation in VAG-COM. It's
just the way the VAG protocols work.
[Done, Go Back] takes you back to the main Control Module screen where you can select
other functions.
12
VAG-COM - Measuring Blocks
(VAG 1551/1552 function 08)
On this screen, you can read all sorts of data from the Control Module in real-time.
Use [Up] and [Dn] to scroll through the available groups (000 - 255 on most Control
Modules) and you can view up to three groups at the same time. Don't become
discouraged when you find some that say "ERROR: Group xxx Not Available" or if you find
some groups where the fields are all blank. Most 1996 and newer ECU's have Groups in
the 200 range, but there are often "gaps" in the numbers.
You can also type a Group number into the Group box and click [Go!]
You can [Log] the data from the measuring blocks. For more information see the Data
Logging section.
13
Measuring Blocks cont.
[Switch to Basic Settings] can be used to go to Basic Settings for the Group that is
currently being displayed. This should be done only under guidance from the Service
Manual or when following some other documented procedure. For more information see
the Basic Settings section.
Note: Multiple Groups are not permitted in Basic Settings. The [Switch To Basic
Settings] button is intentionally disabled if you have groups "running" in the second and
third rows. To stop a running group, click on the box that displays the group number (as
though you wanted to enter a new number). The button is also disabled on controllers using
KWP-2000. On those, you need to go directly to the Basic Settings screen.
The data presented in each Measuring Block Group varies greatly from Control Module to
Control Module and between different models and years. Some groups are documented in
the Factory Repair Manuals, but many are not. Feel free to explore the Control Modules in
your car by scrolling through all the Groups. You can't hurt anything with the Measuring
Blocks function!
VAG-COM will attempt to "scale" the raw data coming from the Control Module into realworld units like degrees C, km/h, etc. At the present time, all scaling conversions are to
metric units.
Note: Group 000 and any other group that displays 10 fields instead of 4 is an
exception. No scaling is possible because the Control Module provides no "Data
Type" information with the data for these. Groups of this type can only be
displayed in the top row of the screen.
VAG-COM also tries to elaborate as much as possible what the data means. Unfortunately,
the "Data Type" information coming from the Control Module is not that precise. For
example: VAG-COM can tell that a particular field contains a Temperature, but the
data from the Controller doesn't tell us whether this is the Coolant Temperature or the
Intake Air Temperature.
To reduce the confusion, VAG-COM supports Label Files and will display the name of the
Label File on the top left corner of the screen. If you click on the name of the Label File, the
file will open in Notepad or whatever program you have set to handle *LBL files. When a
Label file for the Control Module you are looking at does not exist, VAG-COM will come up
with an "educated guess" for what a particular Data Type means. The dealers' VAG-1551
and 1552 scan-tools do not provide any elaboration; they only show what’s in the display
fields!
Group 000 supports special Labels. Due to space constraints on the screen, these labels
are displayed in a "balloon" when the user clicks on a field:
14
Label Files also allow a third label field to be defined for each of the normal measuring
block fields. This label is displayed in a balloon when the user clicks on the field. The idea
is to put "specified values" in this field:
Sample Rate: We can get just over 4.0 samples per second from our '97 VR6 ECU (single
group) with the most aggressive protocol-timing settings. This ECU runs at 9600 baud.
Most newer ECU's run at 10400 and should give proportionately more. Naturally, if two
groups are being displayed simultaneously, the sample rate drops to around 2.0, and 3
groups simultaneously runs at around 1.3. Sample Rate will vary from controller to
controller and the PC used will also have some effect. Some controllers (particularly AG4
transmissions and Digifant-III ECU's) use a "hybrid" data-type that requires reading a long
header when changing group numbers. Viewing multiple groups still works with these data
types, but the sample rate becomes extremely slow. If you see "Reading Header" all the
time under the Sample Rate display, you'll know you've got one of these.
In Engine controllers using KWP-2000, there is a [Turbo] button in the top right of the
Measuring Blocks screen. Pressing this button can significantly speed up sampling, for
example over 30 samples per second when logging a single group in our Touareg. Once
you have pressed [Turbo] you will remain in this High-Speed mode until you exit the
Measuring Blocks screen:
[VAG-Scope] is a plug-in for VAG-COM that allows you to graph Measuring Group
Information. See Appendix C for information on VAG-Scope.
Use [Done, Go Back] to return to the Open Controller screen.
Warning!
If you wish to observe real-time data while driving the car, use a second person who is not
in front of an active airbag!
15
You may also want to try the Advanced Measuring Blocks function (see the table of
contents), which frees you from the grouping format of the Measuring Blocks function.
Acceleration Measurement
When you have one or more measuring group with speed (km/h) in it, clicking on
[Acceleration] will bring up the Acceleration Measurement window, which allows you to
enter start and stop speeds and distances.
After entering the values you want to measure, click [Start] and do your testing.
When complete, click on [Save] to save a copy of your results to your C:\Ross-Tech\VAGCOM\Logs directory
.
16
VAG-COM - Data Logging
You can log the data from the Measuring Blocks screen to a .CSV file. These files can be
opened and analyzed with Excel or other spreadsheet applications.
While the Log Dialog is open;
[Start], [Stop], and [Resume] can all be done with the same button. [Start] begins saving
the data to a log file.
[Stop] discontinues the saving of data to a log file
[Resume] continues the saving of data to a log file.
17
Data Logging cont.
Export RPM Only when checked will record only RPM from the first field and will not
record other fields. Also, this will only record RPM values that are non-zero. This feature
can be useful if you are logging to output the file to a spreadsheet or other third party
software
The [Marker] function places a sequential number in the file when you click the Marker
button. This can be helpful for data analysis.
The [Browse] button allows you to specify the location for your logs. By default, Log Files
will be placed in the Logs sub-folder in your PC, typically: C:\ross-tech\vag-com\Logs\
By default, the name of the log file will be the controller number followed by the number for
each group number that you are logging. The name can be changed to anything you'd like.
If you re-use an existing filename, your new data will be appended to that file.
Switch to Basic Settings is not currently available while logging (but may be added later).
However, you can start a log while you're in Basic Settings. If VAG-COM keeps insisting
that it can't open a Log file, you're probably missing the LOGS folder and should re-install
VAG-COM.
Example using Microsoft Excel:
1. Choose the Measuring Block(s) that you want to view.
2. Click the [Log] button
3. Use default file name if desired. It will append the old file if you use a particular name
more than once.
4. Click [Start]
5. Drive the car through the tests that you want to perform
6. Click [Stop]
7. Click [Done] when you're finished logging data.
8. Open Microsoft Excel
9. Click File->Open (change filetype to all *.*)
10. Locate the *.csv file that you created, typically in C:\ross-tech\vag-com\Logs\
11. With mouse select the columns you want to graph.
12. Click the Chart Wizard button.
13. Select XY (Scatter) and click one of the formats that has lines.
14. The chart wizard will prompt you to name axes if you want.
15. Pick, for example, RPM values for the x-axis and IAT for the y-axis
You can also use the [VAG-Scope] plug-in for VAG-COM that allows you to replay LOG
files. See Appendix C for information on VAG-Scope.
Warning!
If you're going to use VAG-COM while you're driving, please use a second person! Let
one drive while the other observes the data, making sure the person holding the PC is not
in front of an active airbag! Obviously, do not break any laws, speeding or otherwise while
using VAG-COM!
18
VAG-COM - Single Reading
This function allows you to look at real-time data from control modules that support it.
However, the data stream coming from the control module gives NO CLUE what the data
means or how to scale it into real-world values.
The only way to know what the values mean is to find a reference to this function in
the Factory Repair Manual for your car.
This function is rare, but it is used, for example, with some OBD-I 2.8L 12V V6 engines.
The very name of this function annoyed us, so we added a twist. You can look at two
channels of "Single Readings" at once!
Note: On the Open Controller screen, the Supported Codes button will appear in place of
the Single Reading function in modules that support it, since the two functions are mutually
exclusive.
19
VAG-COM – Supported Codes
Supported Codes function: On the latest control modules which have this capability,
VAG-COM can show all DTC and Failure Mode combinations which a control module is
capable of detecting, including the current status of each.
You can sort the results by selecting the radio buttons on the right side of the screen.
Use [OK] to return to the Controller Info / Select Function screen.
Note: On the Open Controller screen, the Supported Codes button will appear in place of
the Single Reading function in modules that support it, since the two functions are mutually
exclusive.
20
VAG-COM - View Readiness
The Readiness Code is a set of 8 bits, each of which corresponds to one monitored
emissions "system" in an OBD-II car. When all readiness bits show "pass", it means that all
systems have been checked and that they pass the on-board tests.
Whenever you clear DTC's or remove power from the ECU, all readiness bits will be set to
"fail". Most cars do not have all 8 systems, so as soon as you apply power again, the bits
corresponding to systems that are not actually in the car will come up "Passed" again.
The above screen-shot was taken immediately after clearing the DTC's. You can see that
this car does not support "monitors" for the EGR, Catalyst Heating, or Air Conditioning
because this specific car does not have EGR or Catalyst Heating. It does have Air
Conditioning, but a "monitor" is only required if the system uses ozone-depleting refrigerant
(R12).
It takes a variety of specific driving conditions to "test" all the systems. It can be done in a
short time using a very specific and complicated procedure found in the On Board
Diagnostic section of the Factory Repair Manual for your engine. The alternative is just to
drive the car for 2-3 days. Make sure you include at least one short highway trip and your
Readiness Bits should all read "Pass" again.
21
View Readiness cont.
VAG-COM also Decodes Readiness bits into meaningful data on modern TDI engines
(a VAG-COM exclusive, not even the VAS-5051/5052 do this!):
Note:
This function is only available on Engine Controllers that are OBD-II compliant (all 1996
and newer US-Model gasoline engines).
Non-US models may not support this function even though they are otherwise OBDII compliant. OBD-I did not require any "monitors".
12V 2.8L V6 engines may have readiness bits stored in or near Measuring Block
Group 029.
22
View Readiness cont.
Support for Guided Readiness Scripts.
Accessible from the Readiness screen, this function will guide the user through the process
of setting Readiness on those engines which support it.
Note: The Guided Readiness Scripts require supporting data in Label files. Support in the
labels shipping with Release 704 is very limited. We hope to have most US-model
engines covered in the near future. If you have a specific engine you would like to see
covered and have a written procedure for it, please email us at [email protected]
Use [Go Back] to return to the Open Controller screen.
23
VAG-COM - Advanced Identification
(VAS 5051/5052 “Identification Services”)
Corresponds to VAS-5051/5051 "Identification Services"
The Advanced ID function is only supported by control modules using the KWP-2000 and
CAN Protocols!
Note: The amount of data appearing on this screen will vary based on what the control
module supports. "N/A" in red means that data isn't available from that module. Some
fields (like Chassis Number) may be blank if the module has never had a chassis number
"installed".
You can use the small [<] and [>] buttons under Software to get version information for
various portions of the firmware in the control module.
Use [Go Back] to return to the Open Controller screen.
24
VAG-COM - Advanced Measuring Blocks
This function expands on the Measuring Blocks function and lets you select up to 12
measuring values from as many as 12 different groups from a selection dialog that shows
the contents of the measuring values. This function is available only when a label file
exists for the control module being accessed.
You can save your selections to a list so that you can quickly access the same measured
values in the future.
Sample Rate: The frequency that the data is updated is determined by the controller in the
vehicle. Selecting a greater number of different Groups will result in slower sampling. In
modules that support it, you can speed up the sample rate by clicking on the [Turbo] button
that is found in Measuring Blocks when reading Engine controllers that run KWP-2000 or
CAN.
[VAG-Scope] is a plug-in for VAG-COM that allows you to graph Measuring Group
Information and display customizable virtual gauges. For more information, see the VAGScope page.
You can [Log] the data from the Advanced Measuring Blocks screen. For more information
see the Data Logging page.
25
Advanced Measuring Blocks cont.
When you have one or more measuring group with speed (km/h) in it, clicking on
[Acceleration] will bring up the Acceleration Measurement window, which allows you to
enter start and stop speeds and distances. After entering the values you want to measure,
click [Start] and do your testing. When complete, click on [Save] to save a copy of your
results to the Logs sub-folder in your PC, typically: C:\ross-tech\vag-com\Logs\
Use [Done, Go Back] to return to the Controller Information screen.
Warning!
If you wish to observe real-time data while driving the car, please use a second person!
Let one drive while the other observes the data, making sure the person holding the PC is
not in front of an active airbag!
Note: You may also want to try the Measuring Blocks function, which accesses the same
data but in a different format.

The Login Function must be used on some (but not all) Control Modules before you can
Recode or change Adaptation values. On others, it "enables" certain features like cruise
control. Valid Login codes can be found in the Factory Repair Manual for your car.
If you are working on an Immobilizer, select [Use 7-digit PIN/SKC] to enter a 7-digit Secret
Key Code. This function is described in its own section.
Balloons: VAG-COM can show Login "charts" when appropriate information is available in
a Label File for the control module in question. The balloon will appear when the mouse
cursor is hovered over the Enter Login Code field.
Use the [Do It!] button to save the Login and return to the Select Function Screen.
Use the [Cancel] button to cancel the Login and return to the Select Function Screen.
This warning appears in the upper right corner
of the screen if a session is disconnected after
you have done a Login. ►
You will need to exit the Controller and do
another Login.
The most common cause of this is the use of an incorrect login code or a 7-digit PIN/SKC
based on an incorrect Immobilizer ID or incorrect data entered in the 7-digit dialog.
27
VAG-COM - 7-digit PIN/SKC
The 7-digit PIN/SKC (Secret Key Code) dialog is used for Key Matching and Immobilizer 3
Adaptation.
You must enter the following information:
•
•
•
•
7-digit SKC that the dealer generated for your exact Immobilizer ID
Number.
Date on which the SKC was GENERATED BY THE DEALER.
Workshop Code (WSC) for the dealer that generated the SKC.
Importer Number for the dealer that generated the SKC.
The 7-digit SKC is useless without ALL of these items.
When you have filled in all of the data click [OK]. If any of
the entered data does not make sense, this message may
appear: ►
When you have successfully submitted the 7-digit PIN/SKC, you are taken back to either
the Login or Adaptation screen (wherever you were when you clicked on
[Use 7-digit PIN/SKC] ). Now, you should have “XXXXX” in Login or Adaptation value.
28
7-digit PIN/SKC cont.
Notes:
Important: Unless you ALREADY have the SKC information for your vehicle and
components then you will NOT be able to do any of the Immobilizer functions. Please
see the FAQ number 4.15 for information on SKC availability.
Unlike the factory diagnostic tools, with VAG-COM, the same PIN can be used for a
particular car at any time in the future, as long as you keep track of the PIN, along with the
Date on which the PIN was GENERATED BY THE DEALER, the dealer's Workshop Code
(WSC) and the Importer number.
If you obtain a 7-digit SKC, but the dealer has not provided the WSC, look at the window
stickers of vehicles on the dealer's lot. The dealer number will be listed next to the name
and address of the dealer. In the US, the dealer number will be a 4 followed by five more
digits, for example 401742. To obtain the WSC, delete the 4 and simply use the remaining
five digits, 01742 in the above example.
The Importer number should be:
444 for all dealerships in the US
999 for all dealerships in Canada
995 for all dealerships in France
Use the [OK] button to save the 7-digit information and return to the Login or Adaptation
screen
Use the [Cancel] button to return to the Login or Adaptation screen without saving.

VAG-COM - Basic Settings
This screen is presented when a Control Module is in Basic Settings mode.
Basic Settings mode is very similar to Measuring Blocks, and the contents of each display
group is the same. The difference between the functions is that the Control Module may try
to perform various calibrations while in Basic Settings mode.
Warning!
You should refer to the Factory Repair Manual for your particular car (or some other
documented procedure) before "playing" with the Basic Settings function. Failure to follow
the proper procedures can result in serious damage to the vehicle.
Although you can use the [Up] and [Dn] buttons to scroll through the available groups just
like on the Measuring Blocks screen, this is probably not a good idea since you may put the
Controller into Basic Settings for a Group that you did not intend.
You can also enter a Group number directly and click [Go!]
[Switch to Meas. Blocks] will switch back to the passive (and "safe") Measuring Blocks
mode.
Notes:
Multiple Groups are not permitted in Basic Settings. The data presented in each Basic
Settings Group varies greatly from Control Module to Control Module and between
different models and years. Some groups are documented in the Factory Repair
Manuals, but many are not.
30
Basic Settings cont.
VAG-COM also tries to elaborate as much as possible what the data means. Unfortunately,
the "Data Type" information coming from the Control Module is not that precise. For
example: VAG-COM can tell that a particular field contains a Temperature, but the
data from the Controller doesn't tell us whether this is the Coolant Temperature or the
Intake Air Temperature. To reduce the confusion, VAG-COM supports Label Files and will
display the name of the Label File on the top left corner of the screen. When a Label file for
the Control Module you are looking at does not exist, VAG-COM will come up with an
"educated guess" for what a particular Data Type means. The dealers' VAG-1551 and 1552
scan-tools do not provide any elaboration; they only show what’s in the display fields! Basic
Setting will display a popup balloon when the mouse if hovered over each value, if the
Label File contains information for that field in that controller. See the Measuring Blocks
section for more information.
The most common use for the Basic Settings function is to recalibrate the Throttle Body.
Another common use for Basic Settings is to bleed the ABS Hydraulic Unit on newer cars.
Please refer to a Factory Repair Manual for your car before attempting to do this!
You can begin and end a Data [Log] while in Basic Settings. See the appropriate section in
this manual for information on Data Logging.
In controllers using KW-1281, the Basic Settings function “does its thing” as soon as you
have entered a group number and clicked [Go] or as soon as you have entered Basic
Settings through the Measuring Blocks function. In Controllers using KWP-2000, there is an
[ON/OFF/Next] button that allows you to initiate and exit Basic Settings while still being
able to see the values in the measuring groups.
31
VAG-COM - Output Tests
The Output Tests function is used to test a Control Module's Electrical Outputs (and the
wiring that connects it to the various devices). Output Tests under KWP-2000 includes
simultaneous measuring data when available from the control module in question.
To begin Output Tests, and to progress through each step, click [Start/Next].
Notes:
The Outputs that can be tested and the sequence in which they become active is controlled
strictly by the Control Module; this is not a function of the Diagnostic Tester. To find out
which Outputs can be tested and the sequence in which they will become active, please
refer to the Factory Repair Manual for your car.
Once the Test Sequence has been started, clicking [Done, Go Back] will take you back to
the Open Controller Function Screen. THE TEST SEQUENCE WILL STILL BE ACTIVE!
Most Control Modules will permit the Output Test Sequence to be run only one time per
session. If you run the Test Sequence to completion, VAG-COM will allow you to return to
the previous screen without closing the session, but you may not be able to run the Output
Test Sequence again. If you need to run the Sequence again, manually Close the
Controller and re-start the session. On some cars, you must cycle the key OFF and ON or
even start the engine (to clear the cylinders of fuel).
Some Outputs require additional action before they become active. Fuel Injectors are a
common example. To activate a Fuel Injector, you must press (and in some cases release)
the gas pedal. Exact details can be found in your Factory Repair Manual.
32
Output Tests cont.
On most systems, the Output Tests function is only available when the Engine is not
running.
It is perfectly normal to see a "short to ground" message in the process of running Output
Tests. The ECU identifies which output it is currently testing by sending a fault-code
number. On many ECU's the full text for this fault code includes "short to ground". Why?
Because one side of the actuator in question has 12V on it all the time and the ECU
completes the circuit (and turns the actuator on) by pulling the other side to ground.
Selective Output Tests. On those modules which support it, this is a more sophisticated
version of the traditional (sequential) Output Test function. It allows the user to select a
particular output and activate it directly without going through a pre-defined sequence to get
there. Some modules have outputs which can only be tested this way. Selective Output
Tests requires supporting data in a label file. There is no way to efficiently query a control
module to find out which outputs are supported.
33
Output Tests cont.
Warning:
Do not use the Output Tests function on any system while the car is in motion! Running
Output Tests on the ABS brake system can temporarily disable the brakes entirely and
cause individual wheels to lock and unlock.
We strongly suggest you refer to the Factory Repair Manual for your specific car before
running Output Tests on any Control Module so you will know what to expect!
If you try to perform Output Tests on an Airbag controller, the following warning will pop up:
For example, in the VW Touareg, a specific procedure must be performed to be able to
start the vehicle if Output Tests on the Airbag Controller have been performed.

Recode is used to set various options in a Control Module.
Warning!
documented procedure) before attempting to Recode a Control Module. At the very least,
write down the original values. There is no other way to "undo" or restore the original
values if what you're trying to do doesn't work out.
Note:
Some Modules require a valid Login before you can re-code them.
A feature unique to VAG-COM: You can leave the WorkShop Code unchanged, or enter
any workshop code you desire. Certain other programs always leave a tell-tale WSC when
you re-code a module.
The Importer Number is only relevant for recoding controllers that use KWP-2000. By
default, this will remain unchanged unless you have set up an Importer Number in the
Options screen.

Long Coding. This function is needed to Recode some control modules (especially
Gateways) in the newest cars that use CAN for diagnostics. Due to the complexity of Long
Coding strings (up to 255 bytes of hexadecimal data) we've accommodated (and urge) the
use of Copy & Paste in this function and usage of the Long Coding Helper.
Long Coding Helper is used with applications such as Niels Ezerman's excellent
LCode.exe (included with this distribution of VAG-COM):
Use the [Transfer Coding] button to send the coding from LCode to the New coding
section of the Long Coding Screen.

available Adaptation Channels are totally undocumented!
You can use the [Up] and [Dn] buttons next to Channel Number to scroll through all 99
possible channels, or you can manually enter a channel number and click [Read]. If a
channel exists, VAG-COM will show you the Stored Value. If a channel does not exist, the
Stored Value will show as "N/A". Other data the controller may or may not send will be
decoded and shown in the four display fields at the top of the screen.
Once you have reached a channel of interest, you can use the [Up] and [Dn] buttons next
to New Value to incrementally change the value. Or you can directly enter a New Value
and click [Test]. This will tell the controller to temporarily use the new value so you can
evaluate it's effects.
When you are satisfied with the effect of a New Value, you can store it in the Controller
permanently by clicking [Save].

Notes:
Channel 00 is a special case. Performing a [Save] to Channel 00 resets all adaptation
values to their original factory defaults. This only works in controllers that support this
function, see your Factory Repair Manual to find out if this procedure applies to each
controller in your vehicle.
Some Engine and Immobilizer controllers will require a valid Login before permitting you to

VAG-COM – Auto Scan
This function scans each controller in the vehicle to retrieve controller information (VAG
number, Component number, Soft. Coding, WSC, and fault codes).
First, you must Select Chassis Type:
There are dozens of different control modules that exist across the entire range of VW/Audi
vehicles. No one car has all Modules! Newer cars have more, older cars have fewer.
Because of this, you must select a Chassis Type that contains only those modules that are
plausible for a given chassis. In general, the chassis type is found in the 7th and 8th digits of
the VIN number.
If you select Auto Detect (CAN Only) as the Chassis Type on newer cars which have a
fully CAN-based diagnostic system, VAG-COM can automatically determine which modules
are installed in a particular car and perform an Auto-Scan of exactly those modules. This
can make the Auto-Scan considerably faster.
There is a file in the VAG-COM directory called AutoScan.txt, which contains all of the
vehicle profiles. It can be edited by simply clicking on the hyperlink above the Chassis Type
selection. This will open the file in your default Text editor (like Notepad) to create a custom
profile for your vehicle. To help you figure out which controllers are in your car, you can run
the Control Module Finder.
43
Auto Scan cont.
The Display Freeze Frame Data checkbox adds Freeze Frame data for Fault Codes on
control modules using the KWP-2000 protocols. Note: Not all control modules fully support
this; very few cars can currently handle freeze-frame data using the VAG proprietary
protocols.
[Start]
This begins the Auto Scan. Be aware; this process can take several minutes. While the
scan is running, VAG-COM will cycle through the Open Controller and Fault Code screens
for each controller before returning to the Auto Scan screen. On newer control modules
which have different Hardware and Software part numbers, Auto-Scan includes the
Hardware Part Number as shown in the screenshots. Double-clicking on any of the Control
Module names in RED will open the Fault Codes screen for that controller and allow you to

VAG-COM – Generic OBD2
(VAG 1551/1552 Address Word 33)
Generic OBD-II functionality. Because many of VW's recent factory repair manuals no
longer have traditional 01-Engine "On Board Diagnostic" information and have replaced it
with "Generic Scan Tool" data, this has become much more important than it was in the
past. Click each of the Mode buttons to accessr each OBD-II function.
Generic OBD-II functionality is "Supported" only on VW, Audi, Seat, and Skoda
cars. It will likely work on many other brands of cars. We'd be happy to receive feedback
as to what other brands and models of cars it does and does not work on, however, we do
not feel obligated to make it work on other manufacturer's cars.
Generic OBD-II functionality is limited to cars using ISO 9141-2 ("CARB"), ISO 14230
("KWP-2000") and ISO-15765 ("CAN") protocols. Our interfaces do not support the
SAE J1850-VPW and J1850-PWM protocols used by most US-market GM and Ford
products, so this cannot work on those cars. Most early (1996-2000) OBD-II compatible
Chrysler cars used ISO-9141-2. Many newer Chrysler cars use SAE-J1850 and are
incompatible. Most European and Asian cars use ISO and should be compatible. In US
models, Generic OBD-II compatibility was required as of model year 1996. In Canada,
1998. In the European Market, 2001 (gasoline-powered) and 2004 (diesel-powered).
Please see the FAQ question 1.10 in Appendix B:
What's the difference between VAG-COM and an OBD-II Scan-Tool?

The [LED’s] button causes the LED on the Interface to blink and may be useful for testing
a port's outputs for troubleshooting certain connection issues.
Protocol Options
55
•
Start Baud is the first baud rate that VAG-COM will try when connecting to a
controller. The current default value is 0. This means VAG-COM will determine
the correct start baud on its own. With our current Interfaces, this field is
unavailable.
•
KW2 Delay has to do with the amount of time used during the initialization of a
session between the PC and the car. The current default value is 30. Do not
change this value from the default unless you are
having difficulties communicating with a particular controller. Contact us for
advice if you are.
•
TST Addr. has to do with the packet addresses used by KWP-2000. The current
default value is -1. Do not change this value from the default unless you are
having difficulties communicating with a particular controller. Contact us for
advice if you are.
•
Debug Level controls how much debugging information VAG-COM records. A
zero in this field (the default) means NO debug output will be generated
whatsoever. This should decrease VAG-COM's susceptibility to interference by
things like virus scanners (except when logging data). There should be no reason
to set Debug to anything other than zero unless you are instructed to do so by
Ross-Tech.
Protocol Options cont.
•
Blk Int affects the protocol timing. The current default value is 55. To get the
highest sample rate possible in the Measuring Blocks screen, set this to 25.
Note, however, that this may cause unreliable communications with some
controllers.
•
Char lnt also affects the protocol timing. The current default value is 1. To get
the highest sample rate possible in the Measuring Blocks screen, set this to 0.
Note, however, that this may cause unreliable communications with some
controllers.
•
KP2 Time only applies to controllers using the KWP-2000 protocol. The current
default value is 25. Decreasing it increases the sample rate in Measuring Blocks
on control modules that use the KWP-2000 protocols. The default value should
be safe for all applications, but if it's not, you can always increase it (to a
maximum of 99).
•
CAN Timeout defines how much longer than normal VAG-Com is going to wait
for the module to respond to a given message. Do not change this value from the
default value of zero unless you are having difficulties communicating with
a particular controller. Contact us for advice if you are.
Init Parameters
•
Bypass OBD-II Fastinit should only be checked if you are experiencing difficulty
connecting to a vehicle using generic OBD-II.
•
Force K on Engine is used on controllers that use the CAN-Bus for diagnostics.
This feature can be useful since the K-line often delivers faster sample rates
while datalogging than does the CAN-Bus on modules that support both. Since
some modules talk only via CAN, this box is unchecked by default.
•
Bypass CAN Init should only be checked if you do not want VAG-COM to try
connecting to vehicles using the CAN-Bus. Force Dumb Mode is used to
prevent VAG-COM from automatically determining the baud rate for
connections..
•
Force Dumb Mode is used to prevent VAG-COM from automatically determining
the baud rate for connections.
Reduce CPU Usage checkboxes will greatly increase responsiveness of other apps
running at the same time as VAG-COM. The disadvantage is somewhat reduced
sample rate.
•
KWP-1281: The default value is unchecked. This reduces CPU usage
when connected to controllers using KWP-1281. Using this feature
*may* make the session with some control modules unreliable.
•
KWP-2000: The default value is unchecked. This reduces CPU usage
when connected to controllers using KWP-2000
[Restore Defaults] will reset all Protocol Options (except WorkShop Code and VZ/Importer
number) to their "as-delivered" settings.

User Interface and Identification
Workshop Identification
•
Shop Name is displayed on reports, such as the Fault Code Report.
•
The WorkShop Code (known as the WSC) is found
on the Admin screen of a dealer's VAS-5051, as well
as on the dealer's stamp. The default value is 00000.
For example, using the stamp below, the dealer's
number is 401/742. To derive the WorkShop Code,
drop the first digit and use the remaining digits in
order. In this example, Evergreen Terrace
Volkswagen has a WSC of 01742. This only applies to
US VW dealers. Canadian dealerships use a 4-digit
number on their stamp. To find the WSC, place a 9
before their number. ►
Note: If you are an individual user or independent mechanic, just leave the WorkShop Code
and VZ/Importer number set to "00000" and “000” respectively. This allows VAG-COM to
operate in “stealth” mode, keeping whatever WSC and VZ that was already in the
controller. If you are using VAG-COM at a Dealership, enter your Dealer's Workshop Code
and VZ. The Work Shop Code and VZ are not easily changed once set on this screen.
Contact us for advice if you need to do so.
•
The VZ/Importer number is essentially a "region code" extension to the Work
Shop Code (should be 444 for US, 999 for Canada). The default value is 000.

The Equipment Number field is used most often when coding new control
modules. Some control modules will refuse being recoded if they're not given an
equipment number (sometimes they require a non-zero WSC and Importer
number too). In those cases, any numbers should work. The default value is
00000.
User Interface
•
256 Color Mode for old PC's This display mode changes the background color
from blue to white, and looks better on some older monitors. The change will take
effect after you close and restart VAG-COM.
•
Left Margin Printing This is the number of spaces that printed pages are shifted
to the right.
•
Window Size This function allows you to change the apparent size of the VAGCOM window on your screen. Adjust this in small increments since it is possible
to make VAG-COM so large that it is much bigger than your screen! To see the
resizing take effect, click Save, then close VAG-COM. When you restart VAGCOM, the new window size should be shown.
[Save] causes the current options to be stored. You need to Save the first time you
use VAG-COM on a PC.
[Apply] lets you use and test the options without storing them.
[Cancel] takes you back to the Main Screen without any effect.

Appendix A: VAG-COM Problems & Issues
Possible Issues, all versions:
•
We have some reports indicating that VAG-COM does not get along with the
Zone Alarm firewall application. If you are using Zone Alarm, turn it off while
using VAG-COM.
•
Virus Scanners: Many virus scanners will adversely affect performance when
logging data and performing other tasks which require VAG-COM to write data to
the disk. If in doubt, turn off virus scanners while using VAG-COM -- your PC
cannot get a virus from your car.
•
Windows 2000: Service Pak 4 is strongly recommended and may be required
when using USB interfaces..
1997 VW Passat B5 Central Convenience System
These controllers seem to have a bug that causes them to drop the communications
session when VAG-COM requests the door-slave controller "Extra" info. A work-around is
available in Version 0.70e which simply does not request any "Extra" info. If you have a
1997 B5 Passat (non-US models only), use 0.70e on the Central Convenience system.
1998 and newer Passats do not have this problem.
1990-1993 VW Cabrio/Cabriolet Airbags
These controllers do not communicate with VAG-COM. In fact, they do not communicate
with Volkswagen's VAG-1552 scan tool either, unless the 1552 has an old, outdated
program card installed.
Audi Concert and Symphony Radios
These are made by Matsushita. The Concerts have blatant bugs in the diagnostic
protocols. We've added one work-around to the low level protocol drivers that works in
some, but not all Concerts, and it is not 100% reliable in any case.
Some Concerts occasionally get "stuck" in an undesirable mode after attempting
communications. If your Concert gets "stuck", the way to reset it is to remove all power
from the radio for at least 10-15 seconds. This can be done by any of these methods:
•
•
•
Removing the radio from the car.
Disconnecting the car's battery
Pulling the fuse for the radio.
Note: Some radios will require you to enter the "security code" using the radio's front panel
after loosing power. See the your owner's manual for the radio for instructions.
It appears that there is something not quite up to snuff in the Symphony's ability to drive
the K-line. We've had some reports that they work better with non-optically isolated
interfaces, and they may work better with the engine running (which means there is a
higher voltage on the VBatt lines in the car).
59
Appendix A: Problems/Issues cont.
1994-1997 Audi C4 (A6/S6) Instrument Clusters
These have a high bit-error rate. We suspect they use a software-UART and "stretch" bits
sometimes. The error-detection/correction logic built into VAG-COM's low-level protocol
drivers as of version 0.70 seems to take care of this in a majority of cases, but we still had
few reports of customers not being able to communicate with these clusters. In version
0.75 or newer, please ensure that Char Int on the Options Screen is set to approximately 3
(which is the default). On some PC's, it may be necessary to adjust this value to
something other than 3. On very fast PC's try a higher value than 3. On very slow PC's, try
a value lower than 3.
We have received reports from users who cleaned the terminals on the wiring connections
at the back of their instrument cluster with electronics cleaner. This appeared to fix the
problem with communicating with these clusters.
1996-1997 Audi A6 2.8L 12V V6 Engine
There is a bug in the Hitachi ECU that does not allow reliable monitoring or logging of
multiple measuring groups. For these vehicles, we recommend only viewing or logging one
group at a time.
2003+ 01J (CVT) Transmissions
These have rather unusual timing requirements. When used with a HEX Interface,
increase Char Int on the Options Screen to approximately 4 or 5.

Appendix B: VAG-COM
Frequently Asked Questions FAQ
1.1 Will VAG-COM work with my car?
VAG-COM will work with most Volkswagen and Audi models sold World-Wide 1994
through 2007. It will work with some cars all the way back to model year 1990. It will also
work with most late-model SEAT, and Skoda models sold in markets other than North
America. If your VW or Audi has a 16-pin "OBD-II style" Data Link Connector, VAG-COM
will definitely work. If your car has the old "2x2" Data Link Connection, check if there is a
wire going to each pin. If there are four wires, VAG-COM should work. If there are only
three, it won't.
Please see these Application Charts at:
www.Ross-Tech.com/vag-com/cars/applications/ where you can select your model and
see which modules can communicate with VAG-COM. Also see the Issues section in
Appendix A for a few things that may not work as expected. If in doubt, e-mail us.
1.2 Will VAG-COM work even if my car is "chipped"?
Yes. If it doesn't work in a "chipped" car, the chip-vendor did something seriously wrong!
Chips from reputable vendors do not interfere with diagnostic functions.
1.3 What functions are included in the current release?
VAG-COM is a software program that turns your PC into sophisticated VW/Audi diagnostic
tool, which performs the functions of the VW/Audi dealers' own tools. Please see the
Function Chart in Appendix E for the current feature set.
1.4 What are the computer requirements?
A computer running Microsoft Windows. A Laptop or "Tablet" computer is best, but a
desktop PC can also be used. See also Question 1.7.
With a Serial interface: We recommend at least a 100 MHz Pentium (or AMD equivalent)
with 16MB of RAM and Windows 95 or newer. Windows 95, 98, ME, NT4, 2000, and XP
are all fine.
With a USB interface: We recommend at least a 500 MHz Pentium-3 (or AMD equivalent)
with 64MB of RAM and Windows 98 or newer. USB interface work best with Windows XP
or newer on a 1 GHz or faster PC. USB interfaces will not work at all with Windows 95 or
NT4.
VAG-COM may work on some lesser PC's, but anything less than the above
recommendations are "unsupported" meaning if it doesn't work, please don't ask us for
help.
Available disk-space should be a non-issue; VAG-COM requires less than 10 MB.
Screen resolution can be as low as 640x480.
If you are using a power supply for a laptop, it should be one specifically designed for that
purpose, NOT a "universal" adapter.
Systems running Windows in a virtualized environment (for example Virtual PC on a Mac)
are not supported. See also Question 1.8.
61
Appendix B: VAG-COM FAQ cont.
1.5 Should I get a Serial or a USB interface?
This depends primarily on the PC you're planning to use:
If you're using a modern PC running Windows XP or Vista, then you should probably
get a USB interface. Although USB interfaces are no faster than serial versions, it's
becoming increasingly difficult to find new PC's with serial ports, so a USB interface is more
future-proof.
If you're using a PC running an older version of Windows or with a CPU speed of
less than 1GHz, we recommend a Serial interface. Obviously a serial interface requires a
Serial Port which looks like this:
Observe the port we surrounded with the GREEN oval. Notice the 9 male pins? That's a
Serial port. Observe the port circled and crossed in RED. Notice the 15 female pins? That
is a Monitor port and will not work!
USB<->Serial converters are often unable to handle the baud rate and timing
requirements that are demanded by many control modules using the VAG protocol. We
have had very poor results with most available USB<->RS-232 converters, therefore
USB<->Serial converters are "Not Supported." Please do not ask us for technical
assistance if you are using one of these converters.
If you want to use one of our Serial interfaces on a PC that doesn't have a serial port, we
recommend you buy a Quatech SSP-100 PCMCIA-Card. We don't sell them, but we've
had excellent results with them. We've got installation and configuration notes here.
http://www.ross-tech.com/vag-com/quatech/index.html
1.6 What if the PC I wish to use with VAG-COM doesn't have Internet access?
To update VAG-COM, you’ll need to download and install the latest version from our
website. Because our updates are provided to you via our download page, rather than on
floppy disks or CD's, you will need a way to transfer the Self-Installing EXE file to the PC
that you will be using with VAG-COM. The file fits easily on a portable USB memory device
and can also be burned onto a CD-R or CD-RW. Make sure that you do not run the EXE
file until you have copied it onto the PC where you would like VAG-COM to be installed.
You do not need to be connected to the Internet while using VAG-COM.
1.7 Can I use VAG-COM on a desk-top computer?
Yes, but you will probably need to use an extension cable (included in the Pro-Kit) which
you can purchase from our web store.
1.8 Will there be a Mac or Linux version?
There will be no "native" Mac or Linux versions. The time and effort required to "port" VAGCOM to these platforms would never be worthwhile. One person has gotten VAG-COM
running under Linux using WINE and another person has managed to get VAG-COM
working on a MAC with Virtual PC. Results on IBM/Motorola Power-PC based Macs using
Virtual PC vary. Some people have gotten it to work, but sample rates tend to be poor and
the sessions tend to drop frequently. This is likely inherent in the overhead and latency
inherent in the virtualized environment. Some people have not gotten it to work at all.
Reports from several people indicate VAG-COM works perfectly on the latest Intel-based
Macs when these run Windows XP natively using Boot Camp
62
1.9 Will there be a Windows-CE/PocketPC/WindowsMobile or Palm-OS version?
Possibly at some point in the future, but we don't have a timetable yet. We conducted a poll
of current and potential VAG-COM users about where we should concentrate development
efforts. The results:
75 % Improving and adding features to the Windows version
11 % Porting VAG-COM to Windows CE / PocketPC
9 % Porting VAG-COM to Palm
3 % Porting VAG-COM to LINUX
2 % Porting VAG-COM to Macintosh
Some of our customers use VAG-COM on a tablet PC such as a Fujitsu Stylistic or on an
ultra-portable PC such as a Toshiba Libretto. These can be purchased inexpensively on
auction sites. These REAL PC's work wonderfully and have very small form factors (the
Libretto is about the size of a VHS video cassette).
1.10 What's the difference between VAG-COM and an OBD-II Scan-Tool?
OBD-II is a government mandated diagnostic protocol that is primarily aimed at diagnosing
emissions-related problems. An OBD-II scan tool will work in many different brands of
cars. VAG-COM uses VW's proprietary diagnostic protocol and will only work in VW/Audi
vehicles. Although you can use an OBD-II Scan Tool in an OBD-II compliant (1996 or
newer) VW or Audi, an OBD-II Scan Tool can only talk to the engine, not the numerous
other "intelligent" systems in the car. Want to reprogram your central locks or your Radio?
Diagnose a problem with your ABS, Airbags, or Automatic Transmission? Re-align your
Immobilizer after swapping ECU's? Reset your Service Reminder Indicators?
Communicate with a pre-1996 model (not OBD-II compliant) car? An OBD-II Scan-Tool
can't do any of these things. Our latest version of VAG-COM adds Generic OBD-II
functionality, see the Generic OBD-II section in this manual for more information.
1.11 Can I use VAG-COM to roll back my electronic odometer?
A: No. A brand new instrument cluster (with less than 100 km on it) can be rolled forward,
one time only. Of course, this assumes that the instrument cluster is "diagnostics capable".
Not all instrument clusters with electronic odometers are.
1.12 Can I use VAG-COM to "Flash" the chip in my ECU?
No, we have investigated flashing, but found that there are several different methods of
encryption for various VW/Audi vehicles, as well as delicate licensing issues to overcome.
Therefore, we do not intend to pursue flashing any further at this time. You cannot alter
boost, timing, fueling, rev limiter, or speed limiter with VAG-COM. You should contact a
chiptuner if you wish to have those parameters altered.
1.13 Is there anything else I need to make full use of VAG-COM?
Yes. A good Factory Repair Manual containing the VAG Scan-Tool procedures for your
car. VAG-COM is a tool, not an on-line service manual. We could not possibly document
everything you can do with it in every year and model of VW/Audi that VAG-COM can be
used with. The most cost-effective manuals with good Scan-Tool procedures for
US/Canadian vehicles are the CD-ROMs from Robert Bentley Publishers. We offer these
at a discount to registered VAG-COM users. Beware, however, that many of the paper
"Service Manuals" published by Bentley do not contain Scan-Tool Procedures. If a paper
Bentley manual is called a "Service Manual" it usually does not have scan-tool procedures.
If it is called "Official Factory Repair Manual", it does. An additional source of manuals that
contain Scan-Tool procedures is Dyment Distribution Services (1-800-544-8021).
Since the above Bentley Factory information only applies to US/Canadian vehicles, if
your car is European-spec or from the rest of the World, they may be of little use to you.

63
2.1 How do I Register/Activate my software?
All of our Current Interfaces have Activation built-in, so VAG-COM should always be Fully
Activated once it has been tested on a car.
2.2 What’s the difference between the Shareware version and the fully registered
version?
When you first download a new version of VAG-COM from our website. it operates in a
limited Shareware mode until you plug in the Interface and test it on a car.
2.3 Is Product Support included in the price?
A: Absolutely. If you have a question or problem, please post it to the VAG-COM mailing
list, mail it to us directly, or give us a call. However, please understand that we don't know
everything about every VW/Audi ever made.
2.4 Why can't I get VAG-COM to communicate at all?
Check the following:
•
•
•
•
•
•
•
•
Is the adapter plugged into the car? A Serial Interface that is not plugged into the car
will always be "Not Found". It gets power from the car!
Is the car's ignition switch in the ON position?
Is it plugged into the correct serial port? Some PC's have the ports mis-labeled.
Are the serial ports on your PC properly configured?
Disable Palm HotSync or Microsoft ActiveSync software!
If you have a 1997 or newer car with an aftermarket radio, read this page:
Check our Issues section in Appendix A for any special configuration settings that may
be necessary for your vehicle
If you are using a power supply for a laptop, it should be one specifically designed for
that purpose, NOT a "universal" adapter.
Note: If you test the COM port, but an hourglass appears, you may have an IRQ conflict.
This may not show up in Device Manager as a conflict. But, try this:
•
Start>Run>MSINFO32.EXE to bring up the System Information utility.
•
Go to Hardware Resources>IRQs This should show a list of all devices by their IRQ,
so you can see if there are any repeated or shared IRQs.
If all else fails, feel free to call or email us, making sure to provide the brand and model of
vehicle, brand and model of PC, and version of VAG-COM.
2.5 VAG-COM communicates, but it's "flaky".
The diagnostic protocols require a degree of real-time response from the diagnostic tool.
Certain other programs and services can prevent VAG-COM from responding in the timely
fashion that the protocols require. Some control modules are fussier about this than
others.
64
2.5 VAG-COM communicates, but it's "flaky". con’t.
Make sure you are using the latest version of VAG-COM. If you have any other programs
running, close them. If you have any of the following active on your computer, turn them
off:
•
•
•
•
•
•
•
Virus Scanners
Task Scheduler
Microsoft Active-Synch
Fast-Find
Some Novell Netware network drivers
Canon "Multipass" multi-function printer/scanner software
Power Management -- some laptops are notoriously difficult, try running the
laptop on AC power!
Other Tips:

Go through all the stuff in your System Tray:
Right-Click on each little icon. If there's a "Disable" or "Exit" option, do it!
Windows 2000 with SP1: Install IE 5.5 or SP2.
Windows 95/98/Me: Pull up a task list by pressing CTRL-ALT-DEL. Kill
everything except Explorer and Systray.
Most versions of Windows: Start -> Run -> MSCONFIG. Take a look at what
other non-essential stuff Windows is loading and disable it.
STOP or remove PCMCIA Cards, especially anything made by Xircom. Some
IBM brand cards are also problematic.
Try turning Off your COM Port's FIFO buffers. Open the properties sheet for the
COM Port in Device Manager. Select the Port Settings tab. Click the Advanced
button. Uncheck the "use FIFO buffer" checkbox.
Some Windows installations, especially ones that have had numerous program
installed and uninstalled over the years may be hopeless. Try installing a clean
copy of Windows in a different folder than the original.
If you have an older, slower PC running Windows XP, try setting the Display
Properties>Appearance to Windows Classic Style instead of Windows XP Style.
If you are using a USB Interface, go to Device Manager, USB Root Hub,
Properties, Power Management, and uncheck "Allow Windows to turn off this
device to save power"
If your PC has multiple Serial or USB ports, try using a different port.
If you have the Window Size on the Options screen in VAG-COM set to to any
value other that 10 (the default) try changing it back to 10 then Test, Save, and
exit out of VAG-COM.
If all else fails, feel free to call or email us, making sure to provide the brand and model of
vehicle, brand and model of PC, and version of VAG-COM.
2.6 Why does my dash BEEP when I access my ABS controller?
In many of the newer models, there will be a series of BEEPs from the dash when you
access the ABS controller (and the ABS light will be ON while you are talking to it). This is
perfectly normal and is done to notify the driver that the ABS is non-functional while in
diagnostic mode.
65
2.7 Are there any Fault-Codes that can and should be ignored?
Yes. Most 1995 and earlier Bosch ECU's will show you a DTC 00513 - Engine Speed
Sensor (G28) if you scan them when the engine is not running. This fault code goes away
by itself once you start the engine. If this sensor were truly defective, the engine would not
run at all! Please ignore this code. In addition, many Automatic Transmission Control
Modules will show a DTC 00526 or 17087 that indicates a faulty brake light switch. This
can also be ignored and will not appear if you press the brakes once before checking for
Fault Codes.
2.8 Are there any known Bugs / Problems / Issues?
Please check the Issues in Appendix A and the Revision History Page online:
http://www.ross-tech.com/vag-com/revisions.html
2.9 What's the Work Shop Code?
Every VW/Audi dealer in the world is assigned a unique Work Shop Code. A brand-new
factory VAG-1551/1552 or VAS-5051/5052 scan tool will not function until a WSC is
entered, and once it has been entered, it cannot be changed. Whenever a Control Module
is Re-Coded, or certain Adaptations are performed, the scan tool sends its WSC to the
control module and the control module records it for posterity. Thus, if a scan-tool is used
to do something like disable certain airbags, in principle it should be possible to tell who
(which dealer) did that. Like the factory scan-tools, VAG-COM will accept a WSC once on
the Options Screen. If you enter a WSC there, it will be sent to the control modules exactly
like it's supposed to be. If you leave the WSC on the Options Screen at its default of
00000, VAG-COM will operate in "stealth mode". Instead of sending a fixed WSC, it will put
back whatever was already in the control module, with one exception: If it finds the
"telltale" WSC (30011) that VWTool/VDS-PRO likes to leave behind, VAG-COM will replace
it with something more innocuous.
2.10 What's with the DEBUG files?
VAG-COM uses these to record a lot of the data being exchanged between the car and
your PC. Having these can be very useful if there is some sort of unexpected problem
communicating with a controller in your car. By default, the Debug Level is set to 0. If
you're having a problem, we may ask you to set the Debug level to something other than
zero, and to send us a specific Debug file. The best way to send Debug files is to ZIP them
first. Contact Ross-Tech if you need assistance doing this.
3.1 Do I need an Interface Adapter?
Yes. The ISO-9141 port in your car is not directly compatible with any standard PC port.
The ISO-9141 port in your car is somewhat RS-232 like, but you can't just wire up a cable -you must put electronics in between to allow a PC to communicate with the car.
3.2 Can I use an Interface adapter that came with another software package?
No, the current version of VAG-COM (versions 500.x and newer) are not compatible with
3rd party interfaces at all, even in shareware mode. To use the latest version of VAG-COM,
you need to use a modern genuine Ross-Tech Interface purchased directly from RossTech or from one of our distributors.
3.3 Can I buy an Interface adapter somewhere else?
66
3.4 Can I build my own Interface Adapter?
3.5 Why does VAG-COM require Activation?
All of our Current Interfaces have Activation built-in so users never have to worry about
Activation, De-Activation, etc. However, VAG-COM versions prior to 5xx.x will also run
through "dumb" interfaces, which are not particularly difficult to make and we would like to
get paid for our work! The reality is that there are many people in this world that just won't
pay for software unless they have to. We've invested a large amount of time and expense
into reverse-engineering the VAG protocols and we're trying to make a living with this
product. Furthermore, we're trying to sell it at a price that makes it affordable to everyone.
The activation scheme is intended to ensure that we get paid by every user, not to make
life difficult for registered customers.
3.6 What if I need to run VAG-COM on more than one PC?
All of our current Interfaces have Activation built-in, so you can download and install VAGCOM onto as many PC's as you'd like, so VAG-COM is fully Registered and Activated once
you test it on a car.
3.7 How do I permanently move VAG-COM from one PC to another?
All of our current Interfaces have Activation built-in, so you can download and install VAGCOM onto as many PC's as you'd like, so VAG-COM is fully Registered and Activated once
you test it on a car. If you need to run VAG-COM on a PC that does not have Internet
access, simply download the installation program from our website and save it onto a CD or
USB drive.
3.8 What's the De-Activate button for? Why would I want to do that?
All of our Current Interfaces have Activation built-in, so there is neither a need nor a choice
to De-Activate.
3.9 Why has VAG-COM become De-Activated on its own?
All of our Current Interfaces have Activation built-in, so VAG-COM should always be Fully
Activated once it has been tested on a car. If you have a Current Interface and VAG-COM
has become De-Activated, please contact us
3.10 Can I sell my VAG-COM System to someone else?
You can sell the hardware, but the software license and support are not transferable. All of
our Current Interfaces act as "dongles" for VAG-COM, so the software should be fully
functional on any PC that meets our requirements. However, we only provide support to
the original purchaser. If you purchase a second-hand "dongle" Interface and want to be a
"registered user" and get technical support, you'll still need to pay $99 to register.
67
4.1 Why and How should I test VAG-COM prior to Activating it?
All of our Current Interfaces that have built-in Activation, are fully Registered and Activated
once you test them on a car. With these Interfaces, the license is built in, you do not have
to Activate VAG-COM, but obviously you'll want to test VAG-COM when you get it to make
sure everything works properly. First, Download and install VAG-COM on your PC. Find
your vehicle on the Applications Page to see which control modules are in your car.
Connect your Interface to your car's Diagnostic Port and to your PC. Turn the ignition ON
(turn the key so the Instrument Cluster lights up, but do not start the car -OR- start the car).
Go into the Options screen, select the correct port, and click the TEST button. Ensure that
VAG-COM finds your interface, you should see a message that says Interface Found. Now
click SAVE. Select one of your car's Control Modules (note: your car will not have all the
Control Modules listed in VAG-COM, only the ones on your Applications Page). After VAGCOM has Connected, check Fault Codes. Repeat the process for each of your car's Control
Modules. If you encounter problems, please try the FAQ Suggestions first. If you still have
problems, feel free to Contact Us with full details about your PC and vehicle, preferably
while you are in front of both.
4.2 Can I use VAG-COM while I am driving?
We strongly recommend against reading data while driving -- that would be an accident
waiting to happen. Almost everything that changes while you drive can be LOGGED to a
.CSV file, which you can analyze to your heart's content using VAG-Scope or Excel (or a
number of other programs) preferably while the vehicle is not in motion..:-) If you find it
necessary to read data while the vehicle is in motion, we strongly urge you to use a second
person -- one to drive, one to look at the PC. This second person should sit in the back
seat, because a laptop used in the front passenger's seat becomes potentially lethal if an
airbag drives it back into the passenger's head or torso in case of an accident.
4.3 What is "The Aftermarket Radio Problem"?
If you are working on a 1997 or newer car with an aftermarket radio read this page:
4.4 How do I upgrade my existing VAG-COM software to the newest version?
You should be able to simply Download and install the latest release of VAG-COM in your
PC. Make sure you have exited out of VAG-COM before you install the new version. All of
our Current Interfaces have built-in Activation, so the new version should be fully
Registered and Activated once you test on a car. If you'd like to be notified when a new
version of VAG-COM becomes available, you should sign up for our Announcements List.
If you purchase a genuine Ross-Tech Interface directly from us, or from one of our
Distributors, you are entitled to free software updates for at least one year from date of
purchase.
4.5 What is the purpose of the "OBD-II" button? Why would I want to press it?
See the Generic OBD2 section of this manual for more information on how to use VAGCOM on ISO-9141 compliant OBD2 vehicles. This function nothing to do with the VAG
protocol that VW uses, and the results of this test have nothing to do with VAG-COM
working with any VW/Audi/SEAT/Skoda vehicle. No VW or Audi products prior to model
year 1996 are OBD-II compliant! Please note that most vehicles sold outside of the US are
NOT OBD-II compatible, and even some US-market TDI's are not OBD-II compatible.
4.6 How do I print screens or data in VAG-COM?
You can print reports from VAG-COM's Fault Code, Auto-Scan, Control Module Finder, and
Gateway Installation screens. You can save data to a Log file and print using a
spreadsheet program. To print screens, we highly recommend the free HardCopy program.
68
4.7 What are Label Files?
In Measuring Blocks, Basic Settings, Adaptation, or Recode, VAG-COM tries to elaborate
as much as possible what the data means. Unfortunately, the "Data Type" information
coming from the Control Module is not that precise. For example: VAG-COM can tell that a
particular field contains a Temperature, but the data from the Controller doesn't tell us
whether this is the Coolant Temperature or the Intake Air Temperature.
To reduce the confusion, VAG-COM supports Label Files and which provide more
information about the data being displayed in Measuring Blocks and can also provide
additional information for the Coding function and Adaptation Channels. When a Label file
for the Control Module you are looking at does not exist, VAG-COM will base the
elaboration on an "educated guess" as to what a particular Data Type means.

4.8 How can I speed up my sample rate in VAG-COM?
The sample rate at which you can view and log data is largely determined by each
controller in the car. There are a few things you can do to speed up the rate for a given
controller. First, logging one group at a time, rather than two or three, will help greatly. In
order to get the highest sample rate possible go to the Options screen and set Blk Int to 25
and Char Int to 0. Note, however, that this may cause unreliable communications with
some controllers. The KP2 Time parameter only applies to controllers using the KWP-2000
protocol. Decreasing it speeds up the sample rate in Measuring Blocks on control modules
that use the KWP-2000 protocols. Try setting it to 0. If any of these adjustments cause
unreliable communications, change them back closer to the defaults. If in doubt, use the
Restore Defaults button! In Engine controllers using KWP-2000, there is a [Turbo] button in
the latest version of VAG-COM. This can significantly speed up sampling, in some cases to
over 30 samples per second. See the Measuring Blocks page for more information.
4.9 What kinds of cool stuff can I do with VAG-COM? See our Car Info & Procedures
Page where you can look up Vehicle Specific Application Charts for your car to see which
control modules exist and can communicate with VAG-COM. Additionally, there are some
very useful links to pages about Key Matching, Immobilizers, as well as some excellent
spreadsheets submitted by our customers.

4.10 How do I set up my USB Interface?
To use one of our USB Interfaces, you'll need to download and install the latest version
VAG-COM with USB Support. After you have installed VAG-COM, you will need to follow
the instructions in the Getting Started section of this manual.

4.11 Does Ross-Tech make diagnostic software for other makes of cars?
Ross-Tech has plans to introduce a diagnostic package for BMW/MINI and we have put
considerable effort into its development. However we've come to realize that before this
product can meet the high standards that our customers have come to expect from VAGCOM, it will require considerably more time and resources than originally planned.
Therefore the BMW/Mini product release is not imminent. As this situation changes, we will
update this FAQ entry with the relevant information and will post announcements on our
News page.
We do not currently have plans to develop manufacturer-specific software for any other
makes of cars, but of course, all plans are subject to change.
We do not know of any other makers of similar software for other makes of vehicles. Our
latest Version of VAG-COM adds Generic OBD-II functionality, see the OBD-II Page for
more info.
4.12 Can I use VAG-COM to retrieve my Radio Code to get it out of "SAFE" mode?
No, You'll need to get the radio code from your dealer (it should also be on a card that
came with your car). Most likely, the dealer will need to physically remove the radio to read
its chassis number, then the chassis number is input into a database at the dealership to
retrieve the radio code. Neither VAG-COM nor the factory scan tools can retrieve the radio
code for you.
4.13 Does VAG-COM work with cars that require direct CAN access for diagnostics?
Yes! We have integrated CAN compatibility into the latest version of VAG-COM, but since
CAN uses different hardware, new interfaces are required. The HEX-COM+CAN and
HEX-USB+CAN interfaces (which are included in the Pro-Kit are fully compatible with the
latest cars that require a direct CAN connection as well as being backwards-compatible
with the older cars that use k-lines. The Mk5 based vehicles like the Rabbit and Jetta can
use a lower priced Micro-CAN as well. Check out our CAN-Bus page for more information:
http://www.ross-tech.com/vag-com/canbus.html
4.14 Can I use VAG-COM to make my windows roll up and down using my keyfob
remote?
Many Audi vehicles can be recoded to allow this function, see this example. Unfortunately,
most VW models do not have the same capability except the Mk5 Golf platform cars and
the B6 Passat. In order to make your windows roll up and down using your remote in an
older VW, you'll need to add extra hardware such as the Remote Window Controller from:

4.15 How do I obtain an SKC for Immobilizer and Key-Matching functions?
We do not know of any way to retrieve an SKC for VW/Audi/SEAT/Skoda vehicles other
than getting it from an official dealership. Prior to 2002, some vehicles were delivered with
a 4-digit SKC on a scratch-off panel on a plastic tag. Starting in 2002, dealerships
implemented the WIN2 system to provide 7-digit SKC's to their technicians and customers.
Recently, many dealerships have switched to the new GEKO system, whereby their factory
scan tools dial up the factory while connected to a car. Under this system, the technician no
longer sees the SKC at all. VAG-COM does not interact with the GEKO system.

Appendix D: VAG-Scope
Graphing "Plug-In" for VAG-COM
75
Appendix D: VAG-Scope cont.
Quick Instructions:
•
You can use VAG-Scope in one of two ways: Allow VAG-COM to launch VAGScope by clicking the [VAG-Scope] button on the Measuring Blocks screen, or
manually start VAG-Scope in stand-alone mode to play back VAG-COM Log
Files. You cannot do both at the same time. If VAG-Scope is running in Standalone mode, VAG-COM will not start. If you manually start VAG-Scope while
VAG-COM is running, it will probably complain.
•
Use the checkboxes next to each display field to select which items are graphed.
•
Click on a field to select it for vertical scaling. VagScope will remember all
scaling values for a particular control module by part number.
•
Click the Ross-Tech Icon for a menu item to access a Preferences Dialog:
Preferences:
•
Here you can set colors for the graph lines, the graph background and the grid.
•
You can also set default scaling values (based on the units that VAG-COM
sends)
NOTE:
VAG-Scope can be used to play back Log files produced by any version of VAG-COM.
VAG-Scope included in the latest VAG-COM release on our Download page.
Right-click on the color box to open up a
gauge for that value.

VAG-Scope -- FAQ:
Q: What are those numbers on the left of the graph?
A: They are the scaling numbers. They define the min and max values that will be graphed
in the window. For instance, a temperature could be graphed between -10 and 130*C.
Q: Great, but I don't like the current ones.
A: Don't worry, everything is fully customizable. You have two different ways of choosing
your scaling factors:
•
In the preferences screen, you can either modify the values for an existing units,
or add a new unit with its values. Make sure the unit is spelled exactly (including
the case) as it appears in the measuring blocks/graphing data.
•
In the main screen, click on a field (or use the blue horizontal arrow) to display its
scaling values. The field you're working on is surrounded by a frame. You can
then change the min and max scaling factors for this particular field
Both settings are saved, so that next time you won't have to do it all over again!
Q: So what's the difference between these two different ways?
A: First, you need to understand how the values are stored/retrieved. When Vag-Scope
graphs data from a controller it doesn't know, it applies the values in the preferences
screen, for the units that are defined. If a unit is "unknown", the min will be 0 and the max
will be 100.
Setting the values in the main screen allows you to override these defaults. For instance,
let's say you set the rpm (/min) value in the preferences screen at 7000. This is fine for
gasoline engines. But a friend visits you with his TDI. What you do is you set the /min fields
in the main screen at 4500, to keep a good resolution in your graph.
At that point, as soon as you stop graphing, the values are stored in the "scaling" directory,
in a file named by the controller part number. And next time you connect to the same
controller, VAG-Scope will automatically remember your settings.
Q: What's the deal with the horizontal scaling?
A: This enables you to tell VAG-Scope the value of the horizontal shift (in pixels) each time
a new sample is delivered by VAG-COM. This is customizable because of the range of
sample rates you can experiment with VAG-COM: you can go from 30 samples per second
on a '02 A4 3.0Q (engine, 1 measuring block at a time) to 0.4 on a Eurovan (transmission,
3 measuring blocks). The default is 3, but you may want to increase it if your sample rate is
low. This way your graphs will be more readable.
This value is also saved automatically for each control module.
Q: Why do I have a big blank after I hit "pause" in live mode?
A: This is intentional. It shows the graph has been paused and avoids having a big
discontinuity in the curves (for instance going from 800 to 7500 rpm in 0.2 second...).
The "pause" button ( II ) can be handy to make screenshots of a particular situation, like a
boost spike for example.
77
VAG-Scope – FAQ cont. :
Q: VAG-Scope says "unexpected end of values". What's wrong?
A: At this time, VAG-Scope does not support appended log files. More precisely, it will only
read the first part of them. The solution is to give your files a more specific name than
"LOG-001-003-xxx-xxx" :-)
Q: "This is not an original VAG-COM log file"
A: Guess what, you altered the file in some way. For instance, just reading and saving the
file in excel adds comas to it, and this is what VAG-Scope relies on to parse the file.
Solution: make a copy of the file before you edit it with a program that modifies the comas.
Q: I'd like to write my own VAG-Scope. Is this possible?
A: Yes, that's one of the reasons why VAG-Scope is open source (the other being we don't
want to be bothered by 10 different feature requests a day). VAG-Scope was written using
MS Visual C++ 6 and you will find the source code on our website.
www.ross-tech.com/vag-scope/
Feel free to improve/write your own VAG-Scope and publish it. Obviously your file has to be
called VagScope.exe so that VAG-COM can "spawn" it.
Q: But I can't program/all I know is VB!
A: Then stop complaining or learn! ;-)

Appendix E: TDI Timing Checker
"Plug-In" for VAG-COM
This plug-in allows you to check the injection timing setting on a TDI engine. This needs to
be done after you changed the timing belt and every once in a while to keep tabs on belt
stretch and pump/pulley misalignment. The standard procedure for this is to have the
engine idling at operating temperature (coolant temp >85*C), go to measuring block 000 for
the engine, switch to basic settings and report fields #2 (injection timing) and #9 (fuel
temperature) on a special graph.
This plug-in reports the timing on the graph in real-time, so you don't need to have your
manual sitting on your lap at the same time. The application also gives you a comment in
the "result" field, that will tell you if all the conditions are fulfilled to check the timing (some
people don't realize you need to have the engine running, for instance...) and if your timing
is within specs or not.
The history of the last 100 samples is displayed as a "cloud" of points. From the size and
shape of this "cloud" you can see how much "jumping around" your engine is doing, and
your average timing is probably right in the middle of the cloud.
